PURPOSE: A ventilation cap is provided to secure an agreeable wearing effect through temperature adjustment and discharge of sweat. CONSTITUTION: A ventilation cap comprises a liner, an outer cover(22), a ventilating hole(12), an air path(13), and a cap visor(11). The liner is formed in a polymer structure and has permeability. The outer cover is exposed to the outside of the cap. The ventilating hole circulates hot air of the inside and cool air of the outside. The air path injects the cool air of the outside into the polymer structure and discharges the hot air of the inside. The cap visor shields the sunlight. |
